'88 tbird eec power relay location

Does anyone know where the eec power relay is on an 1988 thunderbird 5.0L please. A schematic would be great if possible.

 Thank you,
  Mike

Thanks for the info!
I think mine might be causing a voltage drop to the eec

Yes it is a tc.

For the TC, it's soldered inside the IRCM... Not really replaceable unless you can solder and add wiring to feed a external relay...

If you listen closely, you may hear it click five seconds after you turn the key off.
It has a five second delayed drop out.
